We have found two scenarios in which navigating to a List Screen causes a large gray box to appear on the right side of the body section of the list screen.
1. When a user is on a List Screen and switches files to print (calling a script in another file that displays a layout in that secondary file) When they come back to the original List Screen it has the gray box. (consistently happens)
2. When a user navigates to a List Screen in another file using Go To Related Records. (inconsistently happens)
